Dgraph not starting with error: 'Rapid updates are not supported for datasets that do not have a record specification model specified in the record spec file'

Endeca는 인덱싱을 할 때 순서대로 각각의 컴포넌트들을 실행하는데 그 과정중에 하나가 Dgraph를 stop -> start를 하는 것이다.

그런데 로칼에서 webcrawling 을 샘플로 만들어 돌리는데 Dgraph이 실행되질 않았다.

뭐거 문젠가 싶어서 eDen에서 찾아보닸다.

역쉬나 나와 같은 에러가 있었다. ㅋㅋ

-----Problem-----
The Dgraph fails to start with the following errors in the dgraph error log:

Rapid updates enabled and will be read from "appdir/data/dgraphs/Dgraph1/dgraph_input/updates".
Reading binary dataset /appdir/data/dgraphs/Dgraph1/dgraph_input/projectprefix.store

-----Cause -----
This message indicates that your dgraph has the --updatedir flag specified in its startup options, but your project files do not currently have a record specifier property defined. This can happen when adding your own pipeline to a project deployed with the deployment template, which by default is configured to support partial updates.

-----Solution -----
'Rapid updates are not supported for datasets that do not have a record specification model specified in the record spec file.'

If you plan on using partial updates, define a record specifier property in your project.

If you don't plan to use partial update, remove the <update-dir> element from all dgraph components defined in your AppConfig.xml.
